Photography calculations

All AparatTo calculators

Every tool explains its method, limitations and data-dependent result. Results are starting points, not technical guarantees.

Calculate near limit, far limit and total depth of field.

Calculate hyperfocal distance and the nearest acceptable focus limit.

Check angles of view and frame size for a chosen lens.

Compare field of view and depth of field between sensor formats.

Recalculate shutter speed after changing aperture and ISO.

Calculate a new exposure time after adding an ND filter.

Estimate the maximum shutter time before visible star trails.

Calculate frames, capture duration and storage.

Estimate photo count or video duration on a memory card.

Check maximum print size at a chosen PPI.

Estimate how many frames are needed to cover a chosen angle.

Calculate flash range or required aperture.

Estimate magnification, subject field and effective aperture.

Estimate shutter speed for transverse motion.

Choose focal length from distance and desired framing width.

Compare Airy disk diameter with pixel pitch.
